    Omise Pro is a software development company specializing in end-to-end project delivery and digital transformation.

    We partner with clients to design, build, and implement technology solutions that support their business goals. This role is part of our delivery organization, working directly with client teams to execute software projects successfully.

    You will be joining Omise Pro, Omise’s professional services team, working on custom software delivery and digital transformation projects.

    What you will be doing

    We need a strong Senior Backend Engineer to act as a technical anchor and "bar raiser." You will take full ownership of features from design to deployment, proactively eliminate technical debt, and cleanly communicate risks to stakeholders.

    • Architecture: Deep OOP knowledge with proof of building high-concurrency, event-driven systems (CQRS, SAGA).

    • Ability to effectively communicate within an international team
    • Ability to explain technical context to business users
    • Good command of English (Speaking, Writing, and Reading)
